You will NOT have fun.
The enemy AI has superhuman senses and will kill you instantly, occasionally througth walls or accross the map.
The narrative of the missions is awful. Whatever you THINK the mission will be like from reading the briefing is irrelevant. Each mission is designed to be a slaughterhouse. The briefing says there was a failed robbery at a small store? -> 10 suspects armed with automatic guns.

If you expect to find a successor to a game like SWAT4 you are not at the right place.

Good game and if you pay for premium the progression isn't that bad. Ofc that was only changed after the playerbase finally had enough and the games review score tanked.

However you can only enjoy this game if you play russia. Every country except for russia has its vehicles artificially nerfed. Russian vehicles consitently get their best versions in the game. They get upgrades which double the vehicles effectiveness without an increase in battlerating. They get their most modern vehicles, vehicles which aren't even in service yet.
At the same time western and chinese get old vehicles, which at the same time are missing the key feature that made the country produce the vehicle in the first place. This is plainly obvious with the SEP upgrades for the Abrams tanks. It appears that Gaijin thinks "SEP" stands for "same exact protection", even though it is clearly stated by the department of defense and many other sources that the composite armor was improved by some percent.
Other examples of prefferential treatment is the PUMA. The puma features an autocannon that is heavier, more precise and slower firing than the BMPs autocannon. Yet ingame they have comparable precision, they can fire the same amount of time before overheating (which makes no sense because of the fire rate and weight difference). The puma is also denied its AHEAD fuze which would make it a potent close-air-defense asset. The automatic time-fuzing is not implemented at all. Gaijin stated that they wont implement it because the PUMA would be the only vehicle with this capability. Yet at the same time the 2S38 which operates with the exact same mechanism IRL (and isn't even in service yet) gets this capability approximated by receiving proximity-fuzed rounds...
Even more about the PUMA:
It features a soft kill system that would give it a 360° protection against older ATGMs, but again, this has been artificially nerfed into a 50° (iirc) cone. The PUMA is also stated by the producer to be protected against 30mm autocannons (which would be ~100mm RHA) due to its ERA. Yet ingame the ERA gives no protection at all against kinetic ammo, and further, it appears that an ERA which is MUCH bigger and heavier than russian variants gives less protection (hint: the russians are probably lying about theirs).
The bug reporf thread on the forum had almost 400 pages before it got deleted.

As a general rule you can be assured that no vehicle will ever get its defining feature which made our real-world militaries buy it, unless it is a russian vehicle. And even then it is a coin toss if you get it at all, or in a severely gimped version.
